Does V4 pro have vision?

I've been using hermes with deepseek v4 pro for the last couple of months and never had an issue with it analysing images i feed it. A couple of days ago, it stopped being able to analyse images with the below error. I've had to use a Mimo model as an auxiliary for vision as a workaround. Pi and Hermes were both totally confident v4 pro is vision only, but then I don't understand why its worked until now. Any guidance appreciated. V4 Pro is the boss.
